Pete,

I guess I heard bits and pieces of your signal.
A bit later I heard someone calling CQ ON but couldn't get a call.
But QRN is terrible and propagation seems poor, G3KEV and the DI beaccons were weaker than usual.

If it keeps dry I'll give it another try tomorrow.

If WX permits (no rain) I'll try to be QRV tonight (19-21 UT)

Hi Rik and LF
 
Thanks for pushing me into doing some thing about my 500kc/s noise. You would think a bloke my age would have got to grips with this earlier. You were dead right The noise was coming from a DVD player that was on the face of it switched off. Using a small MW radio proved otherwise. I have to pull the plug out of the wall to shut it up. Surgery with a hammer is planned next!!!
 
Oh yes I am now hearing things again hope to hear you and have that QSO.

Hello Pete,


I found out that 90% of the noise on 500kHz came from inside my own
house.

A lot of electronics is running of switched PSU's and you need just
one of

these oscillating near 500 kHz to get a lot of noise.

I took a small portable AM radio (tuned to the lowest end of the
medium wave

band = abt. 520kHz) to locate the noise sources. Use the ferrite
antenna to take

null bearings.

After replacing a couple of 12V switched PSU's by good old linear
ones

noise was down by 10's of dB.

Another source of noise are energy saving lamps. You can locate them
the same

way.

Hi Mal and LF

 

I would like to be on for two way QSO's however its the old
story

here I have a high noise level and am not hearing any thing
other  than local

signals.

 

I was on the Suffolk coast for this years holiday. I only had
a  Kenwood

TS50 and a 40 metre dipole up. I was hearing just about  every
thing on

500kc/s. Its not as though I live in a high density  area apart
from a neighbour

either side the nearest other is about  1/4mile away but I do
have 11kV at the

bottom of the garden which to  date has not been a problem. So I
suspect an

insulator but the noise  is not general it is not affecting HF
at the moment.

 

I have an 8 foot Octagon tuneable and rotatable loop that I
am  playing

with at the moment but so far no real improvement.

 

Sorry for the tale of woe but we are working on the problem.

 

Chris XIZ has suggested X band so I may try that shortly.

Listening on 500 recently it looks like the GAS has gone out.
